Abstract

La présente invention se rapporte à un dispositif de décodage à éléments réfléchissants, qui est destiné à décoder une image codée comportant une image latente codée à l'aide d'au moins un paramètre de codage. Le dispositif selon l'invention comprend un substrat doté d'une partie surface réfléchissante, dont la topographie de surface présente un motif prédéterminé de traits topographiques. Ledit motif prédéterminé est adapté de manière qu'il possède au moins une caractéristique géométrique correspondant audit paramètre de codage, de façon que le placement d'une feuille à transmission lumineuse sur laquelle est formée l'image codée par-dessus le motif prédéterminé de traits topographiques permette la visualisation de l'image latente.
